By disassembling the drive unit on the rotary test stand without disassembling the bearing, performing a rotation test by applying a rotational force from the pinion shaft joint, and detecting the bearing vibration from outside the drive unit and analyzing it. A second method for diagnosing an abnormality of a drive device bearing or the like is known.

The vibration is detected by the vibration detector 11 mounted near the small gear and analyzed by the vibration measuring device 12. This method has an advantage that the drive device can be diagnosed in a non-disassembled state and can be used together with oil flushing in which the drive device is rotated to circulate the internal lubricating oil for cleaning. However, the bearing for the drive unit is a tapered roller bearing, and since there is a gap called end play that absorbs thermal expansion of the shaft in the axial direction, when it is rotated in the unloaded state, it does not rotate with the rolling element of the bearing. There is a problem that the contact with the moving surface is unstable and the vibration cannot be detected stably.
Therefore, a method is adopted in which the rotation speed of the normal rotation test table is increased and the vibration can be detected by utilizing the centrifugal force. However, in order to increase the number of rotations, the equipment of the rotation test stand becomes large and the equipment cost rises.
